Hi People,
If an amplifier delivers 3 watts into a load of matching impedence at 4ohms then 3 watts would be dissipated across the load . However what would be the result of doubling the impedence of the load to 8ohm? The power across the load would not be halved becauseI believe it is a logarithmic relationship. At a guess I think it would be something like 2.4watts but can any one tell me (show me) the equation please?
Thanks in advance,
Willy.
